Hu Liu has been sticking to pencil drawing as the way of her artistic practice. Each piece requires several months to complete and consumes thousands of pencils. Through her works, Hu tries to create another way of viewing: black, as a light-absorbing colour, interacts with the refraction caused by graphite of pencil. Only by taking a close look while wandering through, viewers can observe the texture and veins hiding behind the black. Some hints and lingering marks of the Renaissance and the Northern Song Dynasty painting can be traced in Hu’s drawings. In Hu’s works, single-point perspective from the Renaissance and the scattered perspective from traditional Chinese Shanshui (landscape), are accommodated and deconstructed, which contributes to a scenario where dimension is eliminated. The dark wave rushing down meditates Taoism’s "know the whiteness, keep the blackness" ( means, who knows how white attracts,yet always keeps himself within black's shade).
